An In-vivo Feasibility Study of Laser-based Automatic Irradiance Control in Persons With Superficial Bladder Tumors

The goal of this clinical investigation is to test the sensing and guiding part of the ATLAS system in the human bladder of people with Ta low grade bladder tumors.

The main questions it aims to answer are:

Does the distance sensor of the ATLAS system work as well on human bladder tumor tissue as in normal pig bladder tissue? Does the distance sensor of the ATLAS system work as well on normal human bladder tissue as in normal pig bladder tissue?

Participants will be asked to have their scheduled outpatient laser treatment of bladder tumor(s), detected during surveillance cystoscopy, expanded by approximately 5 minutes.

Inclusion: People with bladder tumor(s) detected during surveillance cystoscopy and booked for outpatient laser treatment of the tumor(s).

Exclusion: Dementia; Persons under 18 years of age; Macroscopic hematuria; Pregnant or breastfeeding women; Expected poor compliance; Persons who do not read or understand Danish.
